The invention relates to the production of non-metallic building materials, providing the raw material base of industrial and civil construction, and can be used, in particular, in the development of deposits of gravel and sand mixtures.

Known device for hydropobic minerals, including a housing made in the form of a pontoon, well hydroporinae projectile mounted on the pontoon with lifting and lowering (see Varens, Bwimage and Donchak. Well hydropobic solid minerals. - M.: Nedra, 1980, p.17-18, 1.5).

The disadvantage of this device is fixed depth of development is determined by the displacement of the pontoon. In the transition to greater depths when the weight hydroporinae of the projectile increases in order to maintain buoyancy of the device you want to increase the displacement of the pontoon.

The closest in technical essence and the achieved result of the claimed device is setup for hydropobic minerals, including a housing made in the form of a pontoon, groundsamine device having Protopriest and placed in the bow of the pontoon crane for lifting and lowering Protopriest, by turning the suction head; it is about an axis placed on the pontoon, and slurry pipeline, the United States is second with gruntsgabalam device (see patent RU No. 2139392, IPC 7 CL E 02 F 3/90. publ. 10.10.1999).

The disadvantage of this device is also fixed depth development.

The problem to which this invention is directed, is to increase the efficiency of development of non-metallic deposits, in particular gravel-sand mixtures (CBC), lying at different depths under water or under a layer of permafrost.

The technical result that can be obtained by the implementation of this invention is to provide opportunities for mineral extraction at varying depths of development.

This technical result is achieved by the fact that in the known installation for hydropobic minerals, including a housing made in the form of a pontoon, groundsamine device having Protopriest placed in the bow of the pontoon crane for lifting and lowering Protopriest, by turning the suction head; it is about an axis placed on the pontoon, and slurry pipeline, coupled with gruntsgabalam device according to the invention, the pontoon is made U-shaped in plan, and are equipped with a mechanism that enables the docking of additional sections to maintain buoyancy by increasing the weight of the suction head; it is, groundsamine device made in the form of borehole guy who radiobiologia of the projectile, crane made a portal, and the axis of rotation located in the middle part of the pontoon.

This set includes all signs, each of which are necessary and together sufficient to achieve the stated technical result, in all cases, use of the invention, which is claimed scope of legal protection.

Installation for hydropobic minerals is illustrated in the drawing, in which figure 1 shows the setup from above, figure 2 - view of the installation from the side, figure 3 - installation from above with four docked additional longitudinal sections, figure 4 - installation with four docked additional longitudinal sections, side view.

Installation for hydropobic minerals consists of a housing made in the form of a U-shaped in plan of the pontoon. The pontoon consists of at least one cross-section 1 the role of a stern section, and rigidly attached thereto two longitudinal sections 2. On the transverse section is the pump 3, the water inlet for washing mineral, engine 4 (electric motor or diesel engine). The engine has a control unit 5.

Two longitudinal sections 2 pontoon mounted with a gap between them, sufficient for lifting and lowering the suction head; it. In the transport position groundsamine device find the camping in a horizontal position above the specified gap. Available part longitudinal sections perform the role of the bow of the pontoon.

The pontoon is equipped with a mechanism (not shown)that enables the snapping additional longitudinal and/or cross-sections to increase its displacement and maintain the buoyancy of the installation when using suction head; it is intended for development of mineral deposits at great depths and having, respectively, a large mass. A mechanism that provides additional snap sections, can be made similar to the mechanism that provides the dock pontoons pontoon-bridge crossing. Can also be used conventional bolted connection.

Groundsamine device made in the form of borehole hydroporinae shell 6 having a monitor 7 for the erosion of minerals, and pulp-raising device 8 with groundoriented 9. Pulp-raising device 8 may be performed, for example, in the form of a hydraulic ejector or airlift. The slurry line of hydraulic ejector or airlift through the ball joint is connected with a floating slurry line.

For lifting and lowering the downhole hydroporinae shell 6 in the bow of the pontoon posted by gantry crane 10 with a winch 11. Lifting and lowering the downhole hydroporinae projectile 8 is produced by rotation from siteline axis, located in the middle part of the pontoon by means of a horizontal hinge 12 mounted on its two longitudinal sections 2.

In the bow and stern of the pontoon installed papilioninae winch 12 to provide maneuvering installation in the pit.

Installation for hydropobic minerals operates as follows.

Gathered in the pit, previously created on the site, or delivered to waterways in the assembled unit is housed on the site intended for development. The ends of the cables papilionini winches anchor on the shore. Well hydroporinae the shell 6 by means of the gantry crane 10 is transferred in the vertical position and start washing out of minerals.

Blurred minerals enters Protopriest and through pulp-raising device 8 rises to the surface and the slurry line is served on a construction site.

With increasing depth the development of increasing rates of water supply and the downhole slurry line hydroporinae projectile 6 and pristykovyvayas two longitudinal pontoon. Extension rods conduit and slurry line is performed after transferring the downhole hydroporinae of the projectile in the horizontal position. To ensure alignment of the pontoon simultaneously with the snap of the longitudinal sections 2 may Ave svoditsya snap additional cross sections 1 pontoon.
